The PM parameters measured at APEX1 were particle size distributions and emission indices for particle number and mass (i.e., the number or mass, respectively, of particles produced per kilogram of fuel burned) , including their volatile and non-volatile fractions.

, the -7B mass-based emission index was found to be four times less than that of the -3B. • NOX measurements were in good agreement with ICAO certification data, indicating that the engines were in good condition and lending credence to the assumption that the concomitant PM emissions are also representative of an engine in good condition.

. The major conclusions reported are broadly consistent with those from the Delta Atlanta-Hartsfield downwind studies.
